When Should I Use Amazon Aurora and When Should I use RDS MySQL?

Now that Database-as-a-service (DBaaS) is in high demand, there is one question regarding AWS services that cannot always be answered easily : When should I use Aurora and when RDS MySQL?

DBaaS cloud services allow users to use databases without configuring physical hardware and infrastructure, and without installing software. I’m not sure if there is a straightforward answer, but when trying to find out which solution best fits an organization there are multiple factors that should be taken into consideration. These may be performance, high availability, operational cost, management, capacity planning, scalability, security, monitoring, etc.

There are also cases where although the workload and operational needs seem to best fit to one solution, there are other limiting factors which may be blockers (or at least need special handling).

In this blog post, I will try to provide some general rules …

How to Automate Minor Version Upgrades for MySQL on RDS

Amazon RDS for MySQL offers the option to automate minor version upgrades using the minor version upgrade policy, a property that lets you decide if Amazon is allowed to perform the upgrades on your behalf. Usually the goal is not to upgrade automatically every RDS instance but to keep up to date automatically non-production deployments. This helps you address engine issues as soon as possible and improve the automation of the deployment process.

If your are using the AWS Command Line Interface (CLI) and you have an instance called test-rds01 it is as simple as changing

[--auto-minor-version-upgrade | --no-auto-minor-version-upgrade]

For example:

aws rds modify-db-instance --db-instance-identifier test-rds01 --apply-immediately …

Encrypting an existing MySQL/MariaDB RDS Instance

Often it is necessary to convert an unencrypted RDS instance into an encrypted one. And it is usually expected that this process is done with minimum or no downtime. Unfortunately, one can only enable encryption when the instance is created. However, there is still hope, as there are a couple of workarounds to encrypt your existing data.

In this article, I will discuss two different solutions to achieve this result.

Solution 1: Create a snapshot and copy the snapshot to a new encrypted snapshot:

  • Create a manual snapshot of the unencrypted RDS instance
  • Go to Snapshots from the left panel and choose the snapshot just created
  • From the Actions, choose Copy snapshot option and enable encryption
  • Select the new encrypted snapshot
  • Go to Actions and …

Is Serverless Just a New Word for Cloud Based?

Serverless is a new buzzword in the database industry. Even though it gets tossed around often, there is some confusion about what it really means and how it really works. Serverless architectures rely on third-party Backend as a Service (BaaS) services. They can also include custom code that is run in managed, ephemeral containers on a Functions as a Service (FaaS) platform. In comparison to traditional Platform as a Service (PaaS) server architecture, where you pay a predetermined sum for your instances, serverless applications benefit from reduced costs of operations and lower complexity. They are also considered to be more agile, allowing for reduced engineering efforts.

In reality, there are still servers in a serverless architecture: they are just being used, managed, and maintained outside of the application. But isn’t that a lot like what cloud providers, such as Amazon RDS, Google Cloud, and Microsoft Azure, are already …

Enabling KMS encryption for a running Amazon RDS instance

Since summer 2017, Amazon RDS supports encryption at rest using AWS Key Management Service (KMS) for db.t2.small and db.t2.medium database instances, making the feature now available to virtually every instance class and type.

Unless you are running Previous Generation DB Instances or you can only afford to run a db.t2.micro, every other instance class now supports native encryption at rest using KMS. As for the Amazon documentation:

Encryption on smaller T2 database instances is useful for development and test use cases, where you want the environment to have identical security …

This Week in Data with Colin Charles 40: a Peak at Blockchain, Lots of MariaDB News, then Back on the Road

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

Shortly after the last dispatch, I jetted off for a spot of vacation (which really meant I was checking out the hype behind Blockchain with a database developer lens at the Blockchain Week NYC), and then some customer visits in Seoul, which explains the short hiatus. Here’s to making this more regular as the summer approaches.

I am about to embark on a fairly long trip, covering a few upcoming appearances: Lisbon for the Percona Engineering meeting, SouthEastLinuxFest in Charlotte, the …

About ZFS Performance

If you are a regular reader of this blog, you likely know I like the ZFS filesystem a lot. ZFS has many very interesting features, but I am a bit tired of hearing negative statements on ZFS performance. It feels a bit like people are telling me “Why do you use InnoDB? I have read that MyISAM is faster.” I found the comparison of InnoDB vs. MyISAM quite interesting, and I’ll use it in this post.

To have some data to support my post, I started an AWS i3.large instance with a 1000GB gp2 EBS volume. A gp2 volume of this size is interesting because it is above the burst IOPS level, so it offers a constant 3000 IOPS performance level.

I used sysbench to create a table of 10M rows and then, using export/import tablespace, I copied it 329 times. I ended up with 330 tables for a total size of about 850GB. The dataset generated by sysbench is not very compressible, so I used lz4 compression in ZFS. …

This Week in Data with Colin Charles 39: a valuable time spent at

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community. 2018 just ended, and it was very enjoyable to be in Bangalore for the conference. The audience was large, the conversations were great, and overall I think this is a rather important conference if you’re into the “DevOps” movement (or are a sysadmin!). From the data store world, Oracle MySQL was a sponsor, as was MyDBOPS (blog), and Elastic. There were plenty more, including Digital Ocean/GoJek/Walmart Labs — many MySQL users.

I took a handful of pictures with people, and here are some of the MyDBOPS team and myself.  They have over 20 …
